What Genetic Testing Should I Request?

Hi all,

After getting a negative biopsy but mixed blood test results, I want to move forward with the genetic testing. (I'm hoping to find that i don't have the genes and can comfortably proceed with a NCGI label.)

However, I've seen some discussion about different genes being considered by different countries...I'm in the US and am seeing my doctor tomorrow. Does anyone have any advice about the specific test to request, including any specific genes and/or testing processes and/or companies/labs?

Also, I would like to be tested for nutrient deficiencies; which nutrients should be tested? My magnesium and B12 were normal several weeks ago, but I want a more comprehensive check.

Thank you so much!

Well, I was really in a pinch when I posted this but was able to do some additional research that I wanted to share. In fact, it came from celiac.com, so it was my oversight!

The information was under Ten Facts about Celiac Disease Genetic Testing (link is here: https://www.celiac.com/articles/21567/1/Ten-Facts-About-Celiac-Disease-Genetic-Testing/Page1.html)

"The absence of any portion of the high-risk genetic patterns DQ2 and DQ8 nearly excludes the possibility of celiac disease with an approximate accuracy of 99.9%. However, there is a big caveat about relying on "negative celiac genetic testing". To definitively declare you have negative celiac genetic tests requires that the laboratory test for and report the presence or absence of the entire HLA DQ genetic pattern, including both alpha and beta subunits. The DQ genetic patterns DQ2 and DQ8 have two subunits but some laboratories only test for the beta subunit. This DQ typing is complicated and difficult to understand even by physicians and scientists. I have written an updated detailed review that appears in the Spring 2008 issue of Scott-Free newsletter published by celiac.com."

So what I took from that is that I should request the genetic testing, which I did today during my appointment, and to help ensure a credible lab result, it's critical to ask that the lab test for both the alpha and beta subunits...to confirm the presence or absence of the entire HLA DQ genetic pattern. If the lab can't do that, then ask your doctor to find a lab that can. If there are other genes that others on here are aware of, please fill me in. I will continue my research and will append this posting if I find something of interest to others.

Also, for those who have been assisting me with my diagnosis process (@ravenwoodglass, @skylark, @rosetapper and several others), I wanted to update you that today I had blood drawn for: total IgA serum, anti-endomysial (EMA) IgA and Vitamin D. I hope to determine whether I have an IgA deficiency. Also, I don't expect my EMA IgA test to be meaningful since I am now gluten-free, but since I only had anti-gliadin IgA tested before, it's more a point of curiosity. Plus, between eating some gluten pre-biopsy, and eating out way too much to successfully avoid all gluten, it is a half-hearted attempt to double-check my blood test.

My doctor was surprisingly receptive to doing the genetic testing and is going to code it so that my insurance understands it is important to evaluate (and will therefore cover it). She's also going to test me for SIBO (at my request). She mentioned that it is key to have a credible clinic/hospital perform the SIBO breath test because the results are subject to rampant diagnosis errors...interesting tidbit.

      Headaches / Migraines and Hypoglycaemia

      This article does not address migraines at all. Yes, red wine and sulfites are often mentioned in connection with migraine triggers. With me, any kind of alcoholic beverage in very modest amounts will reliably produce a migraine. Nitrous oxide generators, which are vaso dialators, also will give me migraines reliably.

      Excessive dietary tyrosine can cause problems. Everything in moderation. Sulfites can also trigger migraines. Sulfites are found in fermented, pickled and aged foods, like cheese. Sulfites cause a high histamine release. High histamine levels are found in migraine. Following a low histamine diet like the low histamine Autoimmune Protocol diet,...

      Then we would need to cut out all meat and fish as they are richer sources of tyrosine than nuts and cheese. Something else about certain tyrosine rich foods must be the actual culprit.

      KAN-101 Treatment for Coeliac Disease

      I agree that KAN-101 looks promising, and hope the fast track is approved. From our article below: "KAN-101 shows promise as an immune tolerance therapy aiming to retrain the immune system, potentially allowing safe gluten exposure in the future, but more clinical data is needed to confirm long-term effects."

      Body dysmorphia experience

      Thank you so much for having the courage to share this incredibly vivid and personal experience; it's a powerful reminder of how physical ailments can disrupt our fundamental sense of self. What you're describing sounds less like a purely psychological body dysmorphia and more like a distinct neurological event, likely triggered by the immense physical stress...

With me, any kind of alcoholic beverage in very modest amounts will reliably produce a migraine. Nitrous oxide generators, which are vaso dialators, also will give me migraines reliably. So, I think most of my migraines are tied to fluctuations vascular tension and blood flow to the brain. That's why the sumatriptan works so well. It is a vaso constrictor.

      Excessive dietary tyrosine can cause problems.  Everything in moderation.   Sulfites can also trigger migraines. Sulfites are found in fermented, pickled and aged foods, like cheese.  Sulfites cause a high histamine release.  High histamine levels are found in migraine.  Following a low histamine diet like the low histamine Autoimmune Protocol diet, a Paleo diet, helps immensely.    Sulfites and other migraine trigger foods can cause changes in the gut microbiome.  These bad bacteria can increase the incidence of migraines, increasing histamine and inflammation leading to increased gut permeability (leaky gut), SIBO, and higher systemic inflammation.   A Ketogenic diet can reduce the incidence of migraine.  A Paleo diet like the AIP diet, that restricts carbohydrates (like from starchy vegetables) becomes a ketogenic diet.  This diet also changes the microbiome, eliminating the bad bacteria and SIBO that cause an increase in histamine, inflammation and migraine.  Fewer bad bacteria reduces inflammation, lowers migraine frequency, and improves leaky gut. Since I started following the low histamine ketogenic AIP paleo diet, I rarely get migraine.  Yes, I do eat carbs occasionally now, rice or potato, but still no migraines.  Feed your body right, feed your intestinal bacteria right, you'll feel better.  Good intestinal bacteria actually make your mental health better, too.  I had to decide to change my diet drastically in order to feel better all the time, not just to satisfy my taste buds.  I chose to eat so I would feel better all the time.  I do like dark chocolate (a migraine trigger), but now I can indulge occasionally without a migraine after.   Microbiota alterations are related to migraine food triggers and inflammatory markers in chronic migraine patients with medication overuse headache https://pmc.ncbi.nlm.nih.gov/articles/PMC11546420/

      Body dysmorphia experience

      By Scott Adams · Posted

      Thank you so much for having the courage to share this incredibly vivid and personal experience; it's a powerful reminder of how physical ailments can disrupt our fundamental sense of self. What you're describing sounds less like a purely psychological body dysmorphia and more like a distinct neurological event, likely triggered by the immense physical stress and inflammation that uncontrolled celiac disease can inflict on the entire body, including the nervous system. It makes complete sense that the specific sensory input—the pressure points of your elbows on your knees—created a temporary, distorted body map in your brain, and the fact that it ceased once you adopted a gluten-free diet is a crucial detail. Your intuition to document this is absolutely right; it's not "crazy" but rather a significant anecdotal data point that underscores the mysterious and far-reaching ways gluten can affect individuals. Your theory about sensory triggers from the feet for others is also a thoughtful insight, and sharing this story could indeed be validating for others who have had similar, unexplainable sensory disturbances, helping them feel less alone in their journey.
